Who each format suits

Countertop-only chocolate makers

If you mainly melt small batches and need to put the hob away afterwards, a portable single-zone model lets you keep the worktop clear between uses. Check that your saucepan fits its stated pan-base range.

Small-kitchen everyday cooks

If the hob must also handle meals using several pans, a four-zone model may suit you, but only where the worktop, space beneath it and electrical arrangement accommodate the installation.

Existing-pan users

If you want to keep your small saucepan, check that a magnet sticks strongly to its base and that the base diameter falls within the chosen hob’s stated limits. Electrolux UK Support recommends the magnet check for induction cookware.

What to check before choosing

Portable single-zone hob

Choose it when: Melting chocolate is an occasional task and the hob needs to be stored after use.

Trade-off: You have one cooking zone, and manual power levels do not set a precise chocolate temperature.

Plug-in four-zone hob

Choose it when: The hob also needs to serve everyday meals using several pans and there is room for a permanent cooking surface.

Trade-off: A supplied plug does not remove the need to check the worktop, space below and electrical loading.

Built-in compact two-zone hob

Choose it when: You want a fixed cooking surface but do not need four zones.

Trade-off: Cut-out, recess and electrical requirements depend on the exact model.

Concern What to check Who this matters to
Gentle-heating control Check the lowest manual setting and whether you can adjust power without relying on presets. Tefal UK lists seven manual levels, from 300W to 2100W, for the Everyday Slim IH210840. I need to heat a small pan gradually rather than choose a hob for its boost setting. Around 42% of consumers put gentle-heating control ahead of their other buying needs.
Space and installation fit For a portable model, check stored dimensions and where its cable will run. For a built-in model, check the worktop cut-out, recess, space below and electrical loading against its installation instructions. If I need the worktop clear after cooking, storage matters; if the hob stays fitted, I need room for it. For about 33% of consumers, space and installation fit are the primary concern.
Pan and electrical suitability Test the pan base with a magnet and compare its diameter with the model’s stated range. For a portable hob, follow the appliance instructions for its socket and keep the lead away from water and heat. I want to keep using my small saucepan without an unsuitable electrical setup. Roughly 25% of consumers give cookware compatibility and safe electrical use priority.

Mistakes to avoid

  • Choosing by boost power alone

    Boost power addresses rapid heating, not the gradual control needed when melting chocolate. Even a published low setting does not establish a fixed chocolate temperature.

    Compare each model’s lowest manual setting and controls, then follow its instructions and stay with the pan while heating.

  • Assuming a small saucepan will work

    Induction needs a magnetic pan base, and a pan below the hob’s stated minimum diameter may not heat as intended.

    Check the base with a magnet, measure the base rather than the rim, and compare it with the exact model’s pan-size limits.

    You may need a different saucepan if the one you own has a non-magnetic base or falls outside those limits.

  • Treating a plug-in built-in hob as a drop-in replacement

    A four-zone appliance still needs suitable worktop space, room beneath it and an appropriate electrical arrangement. Bosch GB lists the PUG61RAA5B at 592 × 522mm, while Joybuy describes the same model as supplied with a 13A plug and a 3.0kW maximum connected load.

    Check the model’s installation sheet against your cut-out, recess and electrical supply; ask a qualified installer to assess any required changes.

    An unsuitable opening or supply may mean worktop changes or an installer visit before the hob can be used.

  • Letting a portable hob’s cable create a hazard

    Electrical Safety First warns that kitchens bring electrical appliances close to water, hot surfaces and trailing leads, and cautions against overloaded sockets.

    Position the appliance and its lead away from water and heat, use the socket arrangement specified in its instructions and do not leave it operating unattended.

Brands and ranges to consider

Tefal

Tefal’s Everyday Slim IH210840 is a portable single-zone option for a kitchen where the hob needs to be stored between uses.

  • Tefal UK lists seven manual levels from 300W to 2100W, pause and timer controls, and compatibility with pans measuring 12cm–26cm.
  • Those settings do not establish a calibrated chocolate-melting temperature; check your pan size and control the heating as you cook.

Bosch

The Series 2 PUG61RAA5B is a four-zone option for a kitchen that needs a permanent hob for meals beyond chocolate melting.

  • Bosch GB lists four zones and dimensions of 51 × 592 × 522mm. Joybuy describes this model as Plug & Play with a supplied 13A plug and a 3.0kW maximum connected load.
  • Check the worktop opening, space below and electrical arrangement before choosing this built-in format.

AEG

AEG UK includes compact two-zone induction hobs alongside larger four- and five-zone models, giving shoppers a fixed-format alternative to a full four-zone layout.

  • The two-zone format is worth considering when a permanent hob is wanted but four cooking zones are unnecessary.
  • AEG UK Support advises checking the cut-out, recess and total electrical loading for the chosen model; its low-power controls also need to be assessed model by model.

Common questions

Will my existing small saucepan work on an induction hob?

It can work if a magnet sticks strongly to its base and the base diameter meets the chosen hob’s stated limits. Electrolux UK Support recommends the magnet test; Tefal UK lists a 12cm–26cm pan range for the Everyday Slim IH210840. Measure the base, not just the rim.

Is a low wattage setting a chocolate-melting setting?

No. A low manual setting gives you a gentler starting point, not a controlled chocolate temperature. Tefal UK lists a 300W–2100W manual range for the Everyday Slim IH210840; follow the appliance instructions, stay with the pan and adjust the heating as needed.

Do I need an electrician for a built-in induction hob?

You may need one if installing the chosen hob requires electrical work or your existing supply needs assessment. AEG UK Support advises checking the model’s total electrical loading, cut-out and recess before installation. Follow the installation instructions and ask a qualified installer to assess any changes needed for your kitchen.

Can I use a portable 2100W induction hob with an extension lead?

Do not assume an extension lead or multi-socket is suitable for a 2100W appliance. Follow the hob’s instructions for its electrical connection; Electrical Safety First warns against overloading sockets and against trailing leads near water or hot surfaces.
